ABSTRACT
One of the common wisecracks in television is,“Looks good here!” It is uttered by someone who is claiming that the signal is fine at that end, and if there is a problem, it must be the fault of the person at the other end of the line. That “other end” may be down the hall from the studio in the tape room or it may be across the country after several microwave links, fiber optic runs, and a satellite hop. Regardless of how complex the ultimate link is, the fact remains that the original signal must be technically correct.
